HTH 91022R Pool Care Kit is a ready-to-use seasonal kit that shocks, prevents algae, controls metals and tests water chemistry for pools up to 20,000 gallons.

Whether preparing your pool for first swim or winterizing at season's end, this all-in-one package delivers the core treatments most pool owners need. The set includes two 1 lb bags of HTH Shock Ultra with calcium hypochlorite, a 12 oz bottle of Algae Guard Granules, a 1.25 lb bottle of Metal & Stain Defense Granules and a pack of HTH Multi-purpose 6-Way Test Strips. It’s formulated to work with both chlorine and saltwater systems and aims to simplify opening and closing tasks while covering common water problems like algae, stains and cloudy water.

How does this kit simplify opening and closing my pool?

The kit groups the essential chemicals into one purchase so you can follow one sequence of treatments during seasonal transitions. Use the included shock to raise free chlorine, Algae Guard to remove or prevent algae blooms and Metal & Stain Defense to chelate metals and inhibit staining. The 6-way test strips help you check key parameters before and after treatment.

• Step-by-step components for opening or closing routines
• Shock treats organic contaminants and boosts chlorine fast
• Algae Guard targets algae growth without extra products
• Test strips monitor chlorine, pH, alkalinity, hardness and CYA

What results will I see after using the HTH pool care kit?

When applied according to the labeled directions, you should see clearer water, reduced algae presence and fewer metal stains over time. Shock raises disinfectant levels to combat bacteria and organics; Algae Guard breaks up and prevents future blooms while Metal & Stain Defense suspends metals to limit staining. The test strips let you verify balance and make follow-up adjustments.

• Improved water clarity after shock and filtration cycles
• Fewer visible algae spots with continued preventive use
• Reduced staining risk on plaster, tile and vinyl surfaces
• Measurable chemistry via 6-way test strips for confident dosing

Is this kit compatible with my pool type and size?

The HTH 91022R kit is formulated to treat up to 20,000 gallons and is compatible with both traditional chlorine and saltwater pools. It provides measured quantities intended for typical residential pools, but very large or heavily contaminated pools may need additional product or staged treatments. Always confirm your pool volume and follow label dosage instructions for the best outcome.

• Treats pools up to 20,000 gallons
• Works with chlorine and saltwater systems
• Add supplemental product for larger capacities or extreme conditions
• Follow on-pack directions for safe, effective dosing

How do I use the included 6-way test strips to guide treatment?

Dip a strip, remove excess water, and read results within the time window specified on the package. The strips measure free chlorine, pH, total alkalinity, total hardness and cyanuric acid (CYA), helping you determine whether to shock, adjust pH/alkalinity or add metal control. Use readings before treatment and again after circulation to confirm progress.

• Measure before dosing to identify which products are needed
• Use results to time shock and algaecide applications correctly
• Re-test after circulation to verify desired levels
• Keep strips dry and store out of direct sunlight for accuracy

Who is this kit for? The HTH 91022R Pool Care Kit is aimed at residential pool owners and caretakers who want a concise, seasonal solution for opening and closing pools up to 20,000 gallons. It’s useful if you prefer a single-box approach that covers shock treatment, algae control, metal/stain prevention and basic water testing without sourcing multiple separate products. For larger commercial pools or extreme contamination, consider consulting a pool professional or using supplemental HTH products.
